The invention relates to the operation of roads, in particular hardware arrangement of a highway to indicate the presence of forced stops on the carriageway.Known warning triangle containing three bands that are connected in a triangle and is equipped with reflective elements, the base with two hinged supports and fasteners (FR patent 2146018, G 09 F 13/00, 1972).The disadvantages of this mn is the falsity of its performance and large volume when folded.The closest analogue of the invention is a device for road signaling that includes a sign for alarm, mounted on a support in the form of an axis for rotation and having a centrifugal speed regulator, the sign for alarm made in the form of a cylinder provided with impellers with supports, each of the impellers are fixed on the surface of the cylinder can be rotated about its own axis parallel to the axis of rotation (SU inventor's certificate 1677149, E 01 F 9/00, 1991).The disadvantage of this device for road signaling is that, because the device is portable, there is a need for a reliable installation on a road barrier and visual perception by the driver of a sign depends on the availability of wind or air flow formed by the moving vehicles that result in movement of the impeller.The technical result of the invention is the provision of increasing the efficiency of visual perception of the sign to signal regardless of weather conditions and distances, automation of operation of the device when the presence of a traffic accident.The technical result is AI, mounted on a support provided with a housing made in the form of a box with swivel cap and plate, located inside the housing and which divides it into upper and lower portions, a cutter mounted in its side wall near the end surface for engagement with cover, removable means for supplying gas at a sign for alarm, mounted on the plate, the shaft with the coils at the ends located in the lower part of the body, the device also has a sensor manual switch to communicate with the actuator mounted on the side wall of the housing, two shock sensor for mounting on road barrier and the nest is made on the side of the box to accommodate the removable mechanism of the rotation shaft, and a sign for alarm is located in the upper part of the box and performed in a sealed chamber made of elastic material with the adapter and the valve placed inside, and with slings, one ends of which are mounted on the camera, and the other is wound on the spool.In addition, the flexible chamber has the shape of a ball or hands, or in the form of eight, and means for supplying gas into the elastic chamber made in the form of a removable core or removable gas container is partially camera can be made of a transparent material to fill her luminous gas.The invention is illustrated in the drawings, in which:

Inside the housing 1 usignoli, made in the form of elastic sealed chamber 5 with the adapter 26 and the valve 6 is placed inside and having openings 7 for the passage of gas and the spring 8. The camera 5 is placed in the upper part of the box when folded, has a bright colored colouring to increase the efficiency of its perception, which is provided by the color material of the camera or by filling the chamber luminous gas such as neon or helium. In this case, the shell chamber 5 is made of transparent material. For better perception of the sign at night you can also use phosphorescent gas. In addition, for efficiency, the perception of the sign to signal the camera can have different forms: in the form of a ball (see Fig.9), hands (see Fig.11) or in the form of eight (see Fig. 10). The chamber 5 is equipped with slings 9, fixed on the surface of the chamber 5 at equal distances from each other, the free ends of which are wound two coils 10, mounted on the rotary shaft 11, is placed in the lower part of the body. In the center of the plate 4 is installed means for supplying gas 12 into the chamber 5 of the sign for alarm, which can be used as a gas generator or gas cylinder of compressed gas. Means for supplying gas 12 ustanovlen in the side wall of the housing 1 at its end surface for engagement with the cover 2. On the other side wall of the housing 1 is made socket 16 with swivel protective screen 17 for the mechanism of rotation 18 of the shaft 11. As a mechanism of rotation of shaft 18 using, for example, a motor to connect it via cable to the onboard network of the car. Instead of the motor you can use any drive, such as a handheld actuator, to ensure rotation of the shaft 11. The device is equipped with a piezoelectric sensor manual switch 14 to communicate with the actuator 13 via an electrical connection 15 and located on the side wall of the housing 1 and the two piezoelectric shock sensor 19 for placing them on a road barrier associated with the actuator 13 and means for supplying gas 12 electrical connection 20. In Fig. 7 and Fig. 8 presents a constructive embodiments of the shock sensor. For example, the shock sensor (see Fig. 7) to install them on a road barrier 22 by any technical means includes a spring-loaded stop 21 mounted with the ability to interact with a spring-loaded pivotally mounted on the barrier 22 and the lever 23. In Fig. 8 shows another variant of the piezoelectric shock sensor, which is carried out in Alminium 24. The housing 1 of the device for road emergency alarm is placed on a support 25 for fixing it on a road barrier 22.The invention is implemented as follows
Road barriers 22 of the roadway to the left and to the right of it at a given distance from each other (see Fig. 12 and Fig. 13) install devices for road emergency alarm and at some distance from the shock sensor 19. Shock sensor, shown in Fig.7, is placed so that the free ends of spring-loaded levers 23 corresponded to the direction of movement of the vehicle. The placement of the shock sensor shown in Fig. 8, does not depend on the direction of movement of vehicles. In case of an accident on the road when the collision of the vehicle with the road barrier 22 from vibration or shock sensor 19, an electric pulse that actuates the actuator 13, resulting in the pivoting of the cover 2 and the implementation of the feed gas from the gas generator or gas compressed gas adapter elastic chamber 5 through the holes 7 and the compressed spring 8 valve 6. As it is filled elastic chamber 5 gas it from a folded state begins to take a defined shape. When specified perugina 8 returns to its original position, returning the valve 6 down, thereby hermetically closing the camera 5. Camera 5, gas-filled, out of the housing 1, rises up and through the sling 9 is located above the box at the specified distance. Fixing camera 5 using the sling 9 allows the character to move through the air, which further increases efficiency of its visual perception and, consequently, more timely warning the driver about the incident ahead of the accident. In this case, since the camera is in different color options, it also increases the effect of preventive perception device that works offline in the event of a road traffic accident. Different color the color of the sign allows you to inform truck drivers about the form, the nature of the emergency situation on the road in this area. For example, the presence of the sign in the air blue informs the driver about the presence of a traffic accident in the left lane, and the red color sign that the accident occurred on the right side of the traffic on the highway. After the accident, when the traffic is restored, the sign for alarm in return for the rotation of the shaft 11. As a mechanism of rotation of the shaft 11, you can use the motor to freewheel, connected by cable to the onboard network of the car. To release gas from the chamber 5 press your finger on the valve 6, which is due to the spring 8 moves, opening holes 7 to release gas. Then the camera 5 is placed in the drawer, closing it with a lid for later use.In the collision of cars in the centre of the road or any other forced stops when there is no impact on road barrier, to ensure the operation of the device for road emergency alarm using the sensor 14 of the manual switch by clicking on it to create electrical pulse, which ensures operation of the actuator and gas supply means 12 into the chamber 5 of the sign, by filling the chamber with gas and release it from the mailbox.Thus, the claimed invention has several advantages over known devices for road safety alarms, because they are constantly posted on the freeway, there is no need for a delivery device at the scene of an accident, provide a sign for alarm automatically provides increased efferox service device by storing the sign for alarm in the closed box in the absence of an emergency on the road. 1.
